Crystal Harris -- Consoled by Dr. Phil's Son

Sources close to Crystal and Jordan tell us Dr. Phil's son gave her a shoulder to cry on when she fled the Playboy Mansion -- but most of their time has been spent in a Hollywood recording studio ... where they are working on Crystal's new album.

Jordan is a singer/songwriter who used to be on the same label as Crystal.

As for dating rumors ... we're told they've been friends for about a year, and even though Crystal's single now -- both of them are ONLY interested in banging out music ... for now.
